FLY-ESCAPE.

Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed September 18, 1911. Serial No. 649,855.

T 0 all whom it may concern;

Be it known that I, GEORGE W. SMITH, a subject of Great Britain, that Ihave taken out my first naturalization papers, residing at Montrose, inthe county of Montrose, State of Colorado, have invented certain new anduseful Improvements in Fly-Escapes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to fly escapes.

The object of the invention resides in the provision of a fly escapeadapted to be associated with windows and capable of being operated frominactive to active positions Zivithout the necessity of opening the win-With the above and other objects in view the invention consists in thedetails 01. construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail reference will be had to theaccompanying drawing wherein like characters of reference denotecorresponding parts in the several views, and in which Figure 1 is afront elevation of a window sash having the improved fly escapeassociated therewith. Fig. 2 a section on the line 2-2 of Fig. 1 showingthe fly escape in closed position, and Fig. 3 a view similar to Fig. 2with the fly escape in open position.

Referring to the drawings, A indicates generally a window sash whichincludes side members 10 and 11, a top 12 and a bottom 13. Mounted inthe sash A is a glass pane 1 1, the upper edge of which terminates shortof the top 12 of the sash and this exposed edge of the pane is protectedby a suitable cap 15. The top 12 of the sash A is provided on its lowerside with a transverse recess 16 disposed in the same plane as the pane1 1 and having its outer portion onlarged as at 17. The lower side ofthe top 12 is provided at its inner end with a depending lip 18 whichcarries a glass pane 19 disposed in spaced relation to the pane 14 andwhich has its lower exposed edge protected by a suitable cap 20.

Movably mounted in the recess 16 is a shutter 21 the lower end of whichterminates in an arcuate portion 22 adapted to seat upon the cap 15 whenthe shutter is dis posed in lowered or closed position. The shutter 21is manipulated through the medium of rods 23 depending from each side ofsaid shutter respectively and guided in eye members 2 1 secured to thelower end o1 the side members 10 and 11 respectively of the sash A. Eachof the rods 23 is pro-- vided with notches 25 and 26 adapted to engagethe eye members respectively so as to lock the shutter 21 in open orclosed position as the case may be. The notches 25 and 26 are adapted tobe held in respective engagement with the eye members 2A by a spring 27anchored to each eye member and bearing against respective rods 23.

In order to set the escape in open position when same is closed as shownin Fig. 2 it is only necessary to press the rods 23 against theinfluence of the spring 27 which will result in the disengagement of thenotch 25 from adjacent eye members 2 1 when an upward pressure on therod 23 will move the shutter 21 into the recess 16 as shown in Fig. 3.When the shutter is in this position the rods 23 are released to theinfluence of the spring 27 when respective notches 26 will engage withrespective eye members and lock the shutter in open position. After thesetting of the shutter 21 in open position the escape of the fliesthrough the space between the cap 15 and the lower edge of the shutteris facilitated by darkening the room.

What is claimed, is

The combination with a window sash having the lower side of its topprovided. with a transverse groove, of a pane mounted in said sashhaving its upper edge terminating short of the top of the sash anddisposed in the same plane as said recess, a shutter slidably mounted inthe recess of the sash for controlling the opening between the upperedge of the pane and the sash, a rod slidably mounted on the sash andhaving one end secured to said shutter and means iEor locking said rodagainst sliding movement when said shutter is disposed in open position.

In testimony whereof I atfix my signature, in presence of two witnesses.
